FreeBSD source keyword statistics

"Inspired by the Linux swear count page I started hacking a quick shell script that retrieves various versions of the FreeBSD src-all distribution and does some statistics on the thing since everybody enjoyes senseless graphs. The graphs shown are generated by tracking the HEAD branch so choppy graphs caused by imports/upgrades of third party applications are expected whereas further forks (i.e. the -stable subtrees) and events on stable trees should not cause any interference."Story
